Tips? Maybe not do it that way
Set angle cut from the front and then stick the dog to the corner.
I much prefer this method than sweeping from one side of the face to the other, especially in smaller trees where you have way less room for error/correction than in a larger tree. Make flat cut, position saw to center and line up visually, progress cut a second or two, double check visually, proceed cut. Once you get used to this method, you can often forget the second visual check, especially if you watch the cut the whole time.
On medium-to-larger trees 16"+, there are a lot of factors, including presence of rot/cat-face, terrain (rocky, loose/duffy, steep, saturated soil, etc...) that may make sweeping the face easier or more difficult than cutting from the center (one point) to the target (two points), though I find myself sweeping more on larger trees. It really all comes down to what is comfortable for the sawyer in the moment.
That being said, it's rare that I use a conventional face. Sometimes on uphill trees, especially if steep, when wanting to keep the butt on the stump so it doesn't roll upon hitting the ground or when swinging smaller trees I will employ a conventional cut. Otherwise, Humboldt.
